Hi 
well I have a 1000H with 2Gb ram and a nice wd 250Gb harddrive. 
Real life battery time depends A LOT on what you do. Wifi of, screen to 50% (wich is realy pretty bright - brighter than my dell xps 1330 at 80%), CPU to power save mode - 6:30 is well possible. 
When you need Wifi and the power mode CPU and like a super bright screen you are down to 4-4.30 I would say.
I think the figure of 7h is true for the eee 901 wihich has the same battery CPU and all that, but a smaller screen and no hard drive, so Asus and other people just use that for the EEE 1000xxx models, too, but that's not quite correct. Still I am quite happy with the battery time...

Cheers

The Asus EeePC 1000H on Hardware Reviews was never tested for battery life. This is wrong. "All day computing", what does that really mean?

Depends what you mean by decent, can run most games at 1280x800 or more on the Asus m50sa. and if you wanna go further you can overclock the CPU and graphics a little when on mains power and get a bit more performance.
